9 els in one direction, so that only one wall of veach of the cylindersand one side of each of the pistons is properly lubricated. It may,

therefore, be; considered the object of this invention to provide asimple means for direct,-

ing a lubricant splashed'by the cranks against the thrust side of themotor, that is,t he side of thecylinder and piston that receives themost wear during the power stroke, so that these portions .of'thepistons and cylinders the pistons and cylinders.

A still further object ofthe invention is the provision of a means forthis-purpose which can'be readily attached to and formed with thepistons and with the engine block below the cylinders'of any known typeof internal combustion engines without interfering with the remainingstructure thereof.

It is a still further object to provide a lubricant system or means forthis purpose which shall be simple in construction, cheap to manufactureand which will perform its purpose with ease, accuracy and efliciency.

The invention will be fully and comprehensively understood from aconsideration of the following detailed description when read inconnection with the, accompanying drawings which form part of theapplication, with the understanding, however, that the improvement iscapable of extended application and is not confined to the exact showingof the drawings nor to the precise construction described and,therefore, such changes and modifications may be made therefrom as donot aifect the spirit of the invention nor exceed the scope thereof asexpressed in the appended claims. I In the drawings: Figure 1 is asectional view through a porwill be efiectively lubricated to preventundue wear and consequent scoring of such sides of tion of enginecylinder to illustrate the application of my improvement, the piston andother partsbeing also in section.

Figure 9 is a sectional view approximately i p on the line 9-9 of Fi ure8, the piston connecting rod being. indicated by the dotted lines? 1 pFigure lOis a front elevation of the lubricant deflectors disclosed inFigures 8 and In Figures 1 and 2 of the drawings the numeral 1designates a cylinder of .an. internal combustion engine, 2 the pistonwhich reciprocates in the cylinder, 3 the'shaft, {l'the crank portion ofthe shaft and 5 the connecting, rod between the crank 45 and the piston2. The piston 2 is of the ordinary construction but in carrying outmyinvent-ion Ieither incal plane and has an'inner flange 7 that istegral'lyfform, bolt, .or weld'therein-a metal *trough'lwhich is broadlyindicated by the numeral 6." The trough, in the showing of the drawingsis substantially semi-cylindri- Secured to the wall of the piston 2."Thef flange may be termed theibooly portion of the trough, the troughproper being somewhat spirally bentin plan to afford an upper porti0n8,whose top is openand a lower or downwardly directed portion 9 whose topmay be closed. "The portion 8 has its end open,but

the end of the part 9 is closed and this part 9 delivers to an oilopening 10 in the piston 2.

The lower portion of the trough is arranged on the thrust side of thepiston and likewise on the thrust side of the cylinder 1.

The crank 4 rotates in the direction of the arrow as disclosed by Figurel of the drawings. On theengine block,'directly below the cylinder 1 andat the said thrustsides of the cylinder and piston I fix in any desiredor preferred manner the inner ends of director elements 11 and 12. Bothof these elements are of the same construction, both being in the natureof channeled elements whose lower faces are open, as at 12, and whosefront faces are arcuate and extended upwardly, as at 13. The topportions of the members 11 are also open, and the closed backs 14 arearranged angularly and are secured to the inner face of the engineblock. From the arcuate front the sides of the lubricant deflectors arearched inwardly as at 15 to provide a clearance for the piston on theextreme down stroke thereof.

In operation the crank, traveling through the pockets therefor in theoil pan picks up and would ordinarily dash such oil against the wallindicated for distinction by the numera-l 16 of the cylinder 1. Thepiston rod travels between the deflector elements 11 and the oil fromthe-crank will be directed through the open bottoms of the saidelements, against the inwardly curved front walls 12 thereof and bedelivered against the second or thrust walls indicated for distinctionby the numeral 17 in the cylinder 1. A portion of the lubricant will, ofcourse, be splashed against the wall 16 and the lubricant 011 the wall17 is received through the opening 10 in the piston upon the downwardstroke thereof and directed into the downwardly rounded or curved troughin the said piston. Also a quantity of oil splashed by the cranks towardthe wall 16 will be delivered into the open top of the trough and willbe of the piston or otherwise effectively secured thereto slightlydiffers from that above de- 7 scribed. The trough comprises an upperdownwardly inclined portion 19 which is widened and which has its topopen. This face is also open.

ure 8 I have illustrated the improvement connected in any suitablemanner in an engine provided with radial cylinders 22. The crank shaftfor the pistons in the cylinder 22 turns in the direction of the arrowdisclosed in c Figure 8 and the lubricant deflector elements, in thisinstance, have their outer walls concaved, as at 23 and the sides oftheir inner faces dished, as at 24, so that the lubricant splashingagainst the curved walls 23 will be directed toward the thrust wall ofthe cylinder 22.

Figure 9 illustrates the manner in which the piston connecting rodtravels between the lubricant deflectors and Figure 10 illustrates inperspective the said deflectors.

The construction and advantages of my improvement will, it is thought,be understoodand appreciated by those skilled in the art to which suchinvention relates so that further description is not required.

Having described the invention, I claim l. Oil dcflectorsdesigned to besecured in an engine directly below the piston cylinder,

arranged in pairs to receive the piston connecting rod therebetween,each comprising a channeled member whose lower face is open and whosefront face 1s curved and extended upwardly into the cylinder and whoseupper 9 2. Oil deflectors designed to be securedin an engine directlybelow the piston cylinder, arranged in pairs to receive the pistonconnecting rod therebetween, each comprising a channeled member whoselower face is open;

and whose front face is curved and extended upwardly into the cylinderand whose upper face is also open and the side walls from the saidopenface of the deflector being arched inwardly to afford a clearancefor the piston on the extremedown stroke of the piston.

In testimony whereof I affix my signature.
